It's impossible to have something colder than absolute zero...right? That's why it's called "absolute zero". Well, it turns out you can get certain substances to negative absolute temperatures (e.g. -1 Kelvin)...but in order to do so,...

A visual for derivatives which generalizes more nicely to topics beyond calculus. Thinking of a function as a transformation, the derivative measure how much that function locally stretches or squishes a given region.

After months of travel, you've arrived at Duonia, home to the famous temple that's the destination of your pilgrimage. The walk from the welcome center to the temple isn't a long one ... but there's a problem. Can you outsmart the city's...

New ReviewIn this video, we build directly on electric potential energy and electric potential to develop a clear, conceptual understanding of electric potential difference. Using parallel plates and a uniform electric field, you will see where...

In this video we are going over the beginning of how to graph a logarithmic function. This is the video you will want to watch first before going deeper.

This video provides a clear and engaging explanation of negative numbers, starting with the concept that they are any number less than 0. The presenter uses relatable examples, such as imagining losing oranges from a bowl until there are...

A video entitled "Solving Logarithms" which walks through how to solve logarithmic equations by setting the insides equal when the logs have the same base.

Pupil outcome: I can read and write negative numbers. Key learning points: - The negative or minus sign in front of a number shows that it is a negative value.

Pupil outcome: I can explain how the value of a number relates to its position from zero. Key learning points: - Negative numbers are below zero on a vertical scale - Negative numbers are to the left of zero on a horizontal scale

Pupil outcome: I can represent a change story using addition and subtraction symbols. Key learning points: - A change can be positive or negative. - A change can be represented by a negative number.

Pupil outcome: I can systematically solve problems with two unknowns with one, several and infinite solutions. Key learning points: - Problems can be represented using bar models. - Problems can be solved using trial and improvement. -...

Pupil outcome: I can identify the same outcome across all the different representations. Key learning points: - Fluency in moving between the representations is important. - Sometimes it is better to display the outcomes using a...

Pupil outcome: I can calculate with roots and integer indices, including estimating the answer. Key learning points: - Integer indices state how often a number should be multiplied by itself. - The square root of any perfect square will...

Pupil outcome: I can compare negative integers using < and >. Key learning points: - Negative integers in context can be ordered. - Negative integers can be represented and compared on a number line. - Negative integer comparisons can be...

Pupil outcome: I can use the mathematical structures that underpin subtraction to add and subtract positive and negative integers. Key learning points: - Any subtraction can be re-written as an equivalent addition. - Subtracting a...

Pupil outcome: I can understand the minimum information required to describe a translation. Key learning points: - A translation can be described in terms of left/right and up/down. - To be more precise, it is useful to have a scale to...

Pupil outcome: I can use the mathematical structures that underpin addition to add positive and negative integers. Key learning points: - It can help to think of a context when doing a calculation. - Addition of negative integers can be...

Pupil outcome: I can compare and contrast the usefulness of the different representations when calculating conditional probabilities. Key learning points: - The same conditional probability can be found from multiple representations -...

Pupil outcome: I can prove the relationship between the gradients of perpendicular lines. Key learning points: - Two lines are perpendicular if they meet at right angles. - The product of the gradients of two perpendicular lines is -1 -...

Pupil outcome: I can represent a set of coordinates, constructed according to a mathematical rule, both algebraically and graphically. Key learning points: - Pairs of coordinates that follow a rule can be found. - Pairs of coordinates...
